Common sense and material requirements for tent use1

There are many types of tents on the market, and the prices vary a lot. According to the altitude of the place of use, it can be divided into two types: alpine tents and low-mountain tents; according to different seasons, it can be divided into spring, summer and autumn tents and four-season tents. Alpine tents are generally full tents, which have strong rainproof, windproof and thermal functions, but their ventilation function is not as good as that of low-altitude tents with half tents. Therefore, high mountain tents are hotter than low mountain tents when used in summer. However, due to the special design, the high mountain tent is very low and can withstand strong storms, while the inner space of the low mountain tent is relatively higher and wider. Due to the different materials used, tents vary greatly in price. Alpine tents are generally made of aluminum alloy tent poles. The poles of this material not only have good toughness, strong cold resistance, and are not easy to break and deform, but also are relatively light. The low mountain tent is cheap because the tent pole is made of carbon plastic fiber, which is slightly less tough and heavier. There are also differences in the price of the rain-proof coating of the outer tent. It is a single layer and quite ventilated. It is a canopy with a nylon bottom. It is a low-altitude camping type. It can resist light rain. The design considerations focus on ventilation followed by weather resistance. Usually the top cover is a ventilated screen mesh. The bottom layer is nylon cloth, with an outer tent. The light color will not make the interior too unbearable from the sun, and it cannot resist the strong wind belt. The outer tent can only withstand the light rain. Three-season use refers to tents used in non-snow seasons. It is different from camp posts. It can resist strong winds and a little snow. Most tents have a breathable nylon inner tent and a waterproof outer tent. The tent door is double-layered. , the first layer is gauze, the moisture inside the tent can leak out, and the tent door is large. This kind of tent is suitable for three days to one week of activities, preferably forests or open camp terrain that will not be too exposed. The material of tents used in the four seasons is relatively hard, which can support snow and strong winds. The double-door type is easy to enter and exit the camp in bad weather. This kind of tent is designed for the problem of equipment access and storage during the snow season and the question of whether the internal and external tent space is enough for cooking. It is quite suitable for forests. Snow season blizzard below the limit. Military tents have strict requirements on materials, workmanship, thickness of support steel and processing methods, and there are many varieties of fabrics. The fabrics of military tents are basically produced after the general production, and there are also some civilian factories, but the fabrics are very different. big difference. The felt used in military tents is military white needle-punched felt, 5MM thick, which contains wool, and the lining is military polyester taffeta Oxford lining 190T. For some civil military tents such as construction military tents, there is no uniform material used. Industry requirements, that is, there are all kinds of materials. So you have to keep your eyes open. Some are made of shoddy and inferior fabrics, and the name is in professional terms. After a dispute occurs, others can also be relieved, but you do not understand it clearly. Defective military tents have a short service life, and some coated fabrics have odors. Especially in the case of long-term exposure to the sun, the smell is strong. Military tents have a long service life and can be used for about 10 years without problems. Good breathability, waterproof and windproof performance. The indicators of some better civilian military tents are also good. This requires buyers to ask clearly when purchasing, and shop around.
